I'm going to jump in here and make an observation.
It sounds like you have too much code in a single
try/except block.  If you have independent calls
to instrument interface put each of them that might
fail in a separate try/except block.  I've needed
to do this in an earlier project and I log errors
in a log file for review.

Something like:

try: data=getsomedatafrominstrumentfunc1()
except:
    logf.writelines("W","Unable to communicate with func1")

try: data=getsomedatafrominstrumentfunc2()
except:
    logf.writelines("W","Unable to communicate with func2")

My understanding is that try/except overhead is very low
(especially if there is not an exception).
